HORSESHOE-CALK.

Specification of Letters Patent.

Patented Oct. 17, 1911.

Application filed February 25, 1911. Serial No. 610,898.

To all whom it may concern:

Be it known that 1, JOHN WV. FISHER, citi' Zen of the United States, residing at Newberry, in the county of Lycoming and State of Pennsylvania, have invented certain new and useful Improvements in Horseshoe- Calks, of which the following is a specification.

My invention relates to improvements in horseshoes and particularly to the provision of removable calks therefor.

In the ordinary form of detachable or removable calk, the body of the calk is provided with a screw which engages the shoe and holds the calk in place upon the shoe. This form of calk is objectionable, for the reason that it is liable to turn and become loose, or else that it is diflicult to attach or detach if the threads of the screw are deformed in order to prevent this rotation.

The primary object of my invention is the provision of a calk which shall not become readily detached from the shoe accidentally, said calk being provided with a core which may be quickly and easily removed or replaced.

Another object of my invention is the provision of a removable calk, the body portion of which consists of two sections, each provided with a screw-threaded pin or stud, each section being adapted to be separately screwed into a perforation in the shoe, the sections being joined after their full engagement with the shoe so as to prevent the section from any rotative movement, and thus hold the calks securely in place.

A further object of the invention is the provision in connection with a body, as described above, of a steel core, removably supported in the body sections and readily detachable therefrom, said steel core being rigidly held in place when in use.

A still further object is to provide means whereby the body sections may be longitudinally adjusted to suit horseshoes of various widths at the toe.

For a full understanding of the invention reference is to be had to the following description and accompanying drawing, in which:

Figure 1 is a perspective view of a horseshoe, the shoe being inverted and my improved calk applied thereto. Fig. 2 is a longitudinal section of a horseshoe showing my improved calk applied thereto. Fig. 3 is a front view of one of my improved calks.

Fig. 4 is a top plan view thereof, and Fig. 5 is a view of one of the calksfithe parts thereof being separated.

Corresponding and like parts are referred to in the following description and inclicated in all the views of the accompanying drawings by the same reference characters.

Referring to these figures, 2 designates a horseshoe of any ordinary form and provided with my improved toe calk. At spaced points upon the toe of the shoe there are provided the screw-threaded perforations 3. The calk proper is composed of two sections 5 and 6, each section being provided with the screw-threaded stud or pin 7 adapted to engage in one of the perforations 3. Each of the sections is composed of a U-shaped piece of metal, preferably steel, the downwardly depending portions 8 0f the sections being spaced apart, as at 9 for the reception of the steel core. Each of the U-shaped body portions is provided with an extended portion 10, these extended portions 10 being a continuation of one of the downward depending legs 8 of the body portion and each extension is formed with a perforation 11. When the sections are placed upon a shoe, one of the extensions 10 overlaps the extension 10 of the other section, and the perforations of both sections are in register with each other. It will be seen from Fig. 4 that these sections are reversely disposed to each other so that the extension of one section fits over the extension of the other section and the end of one extension abuts against the body of the other section.

The core 12 is preferably of hardened steel and has a sharpened lower edge. This core is of such thickness that it fits snugly between the legs 8 of each body portion of the sections and is provided at its middle with an upwardly extending portion 13 which fits between the two sections as illustrated in Fig. 4 and holds them firmly spaced apart. It is also provided with an elongated perforation 14 which, when the core is in position registers with the perforations 11 in the extensions 10. A screw 15 passes through the perforations 13 and 14 and holds the sections of the body portion and the core firmly together. When it is desired to remove the core so that it may be replaced, it is only necessary to remove the screw 15, whereupon the core may be easily drawn out and a new one inserted. When the core is removed, the sections of the body may be easily rotated so as to either screw them up tighter into the shoe or remove them from the shoe. WVhen the core is in place, however, and the sections are bolted, to it, it is obvious that the sections cannot rotate and that they will remain in alinement with each other and be rigidly held by the two sections 7 from any rotative movement relative to the shoe itself.

Of course, I do not wish to limit myself to the eXact shape of the core 12 nor to the exact shape of the core supporting sections, as it is obvious that many minor changes might be made without departing from the spirit of the invention.

I have shown my improved calk as being applied to the toe of a horseshoe, but I wish it to be understood that it might be applied to any other part of the shoe and as many of the calks as desired, may be used.

In order that the sections of the calk may be adjustable to suitthe various widths of horseshoes at the toe, I form the perforation 11 of one of the sections elongated and provide an elongated opening 14: in the core 12-. By this means the sections may be adjusted so that the screw pins will fit in the openings 3 formed for them in the shoe, even though these openings may vary in distance from center to center. These openings will be placed nearer to or farther from each other, depending upon the width of the shoe. While I have shown the screw 15 as provided with a square head, it will of course be understood that any other form of head might be used.

Having thus described the invention what is claimed as new is 1. A calk for horseshoes, comprising a body formed in two sections, each section being provided with a screw threaded stud for engagement with the horseshoe each section having spaced dependlng portions formmg a core-receiving socket, one of said portions of each section being laterally extended and perforated, a removable core having a length equal to the combined length of the two sections, said core fitting in the sockets in the sections and being disposed between the eX- tensions thereof, that part of the core between the extended portions of the sections being extended upward flush with the upper edges of said extensions and perforated, and a screw passing through the perforated extensions and through the perforation of the core.

:2. The combination with a horseshoe having spaced screw-threaded perforations, of a calk therefor having a socket for the reception of a removable core, and a removable core for the socket, said calk being made in two sections, each independently rotatable with relation to the other, and each having a screw-threaded stud engaging one of the perforations of the shoe, the said core acting to hold the sections from independent rotation.

3. A calk for horseshoes including a body formed in two sections, each section having a screw threaded stud and each section having a perforated lateral extension, the perforation of one section being elongated, the

extension of one section overlapping the extension of the other section, a core disposed between the sections and formed with an elongated perforation, and a screw eXtending through the perforations of both of said extensions and through the perforation of the core.

In testimony whereof, I affix my signature in presence of two witnesses.
